Best practice for adding parent-child related ModelVisual3D elements

Posted By:      Posted Date: October 08, 2010    Points: 0   Category :WPF


I have build a WPF application which loads some 3D models. Some of the models have a parent-child relationship, e.g. a tree has some branches and each branch has leaves.

Now I created a class for each type: tree, branch and leave. From within a "branch" object I want to add the leaves with a "AddLeaves()" method. But I don't know what's the best way to access the ViewPort3D object, to which I can add the "leave" objects.

Do I have to implement a "ViewPort3D" member on each class which saves the reference to the viewport? Or is there a easier way to achieve this? Perhaps with DependencyProperies?

How can I access the "children" property of the ViewPort3D object the easiest way?

Please help!!!

InfoPath and Access - two parent tables and one child table


Hi there,

I'm trying to link an InfoPath form to an Access database, I want to connect the InfoPath form to 3 tables in the Access database but InfoPath will only recognise parent-child relationships in a series (e.g. the "Company" table is the parent to the "Customer" table, which is again parent to the "Orders" table)

I need to have two parent tables and one child table, though (e.g. "Customer" is parent to "Orders", but "Inventory_Item" is also parent to "Orders"). Is there any way to establish this in InfoPath? I'm using Windows XP, InfoPath 2007 and Access 2007.

Cheers, Patrick

How to assign data from 1 DataReader into Parent/Child object??

Hi I have a parent & child table. Parent - User UserID UserName Status 1 Shallin A 2 How A   Child - UserAccess UserID Country Default 1 US 0 1 UK 0 1 MY 1 2 SG 0 2 HK 0 2 MY 1   I also have parent & child object class.       I would like to use 1 C# function and 1 SP to handle the retrieve portion but I have 1 problem. I'm not sure how to assign the value from Reader to the object.   I do something like this but I only get 1 country which is the last country. if (dr.HasRows) {     while (dr.Read())     {         User objUser = new User();         objUser.UserID = dr["User_ID"].ToString().Trim();         objUser.UserName = dr["UserName"].ToString().Trim();         objUser.UserStatus = dr["Status"].ToString().Trim();         UserAccess objUserAccess = new UserAccess();         objUserAccess.Country = dr["Country"].ToString().Trim();         objUserAccess.Default = dr["Default"].ToString().Trim();         objUser.UserAccessCollection = new UserA

this.controls.add - not always adding to parent form

My current code (snippet below) iterates through user info and adds the same custom control to a form based on how many "Meals" (1-6) the user has selected.  It appears that all even # controls (the second, fourth and sixth) are added to the previously added control, rather than the parent form, when I later try to dispose the controls by iterating through this.controls, only 1, 3 and 5 appear, the others appear as children to 1, 3 & 5. I've reduced controls size, etc. to make sure they're not overlapping (if that can force inheritence?) but no luck.  Anyone have suggestions on what to look at or other guidance? public void drawMealPanel(Meal m, int x, int y) { Controls.MealDisplay md = new Controls.MealDisplay(m); md.Name = m.name; md.Tag = m.id.ToString(); md.Left = x; md.Top = y; md.DragDrop += new System.Windows.Forms.DragEventHandler(this.MealView_DragDrop); md.DragEnter += new System.Windows.Forms.DragEventHandler(this.MealView_DragEnter); this.Controls.Add(md); }

Help about cascadin M2M with parent child hierachy custom rollup for one measure

Dear MSAS Experts, My name is Andre and i am writing my thesis about data quality which needs to be finished in about 3 weeks.:-( For my thesis i needed to develop a Schema which store data quality issues. This is a part of my schema which includes a cascading M2M: Facttabele: ErrorFact / ChecksFact / RULE ID / ... DT_RULE: Rule_ID / ..... RULE_ATTRIBUTE_BRIDGE: RULE_ID / Attribut_ID => M2M beetween Rule and Attribut(Rules can belong to multiple Attributes) DT_Attribut: Attribut_ID / .... Attribut_KPI_Bridge: Atribute_ID / KPI_ID => M2M beetween Attribute and KPI (Attributes can be used for multible KPI calc) DT_KPI: KPI_ID, KPI_Name, KPI_PARENT => Parent Child Since MSAS do not provide a Agrgatefunction I have a calculated Measure (lets say its called 'EC') which calculates the average of ErrorFact/ChecksFact. Now the problem I do have is that the 'EC' Measure should be aggregated within and only in the DT_KPI dimension that every child which belongs to the same parent should be muliplicated ('*') with each other till we reach the all member node. So if we have the following PC-Hierachy: -A --B ---C ---D --E The result of A would be (C*D)*E = A. B of course would show the result of C*D. On the other hand all the other facts should use the normal aggregation for this dimension. Also EC should be aggregated normal in all other dimensions. I tried usin
